I created a plot in plotly(R) with a secondary y-axis. I use the hoverfunction x unified, but I would love to change the dateformat in the header. The data is weekly data, so now you see in the hoover: 1 jan 2022, but what I want to see is: 1 jan (week 01) or 1 jan - 8 jan 22. I tried some things with tickprefix, but then also the ticks are changing and not only the hover.
My demo code now is:
library(plotly) # dummy data df_data1 = data.frame(date_input = seq(as.Date('2022/01/01'), as.Date('2022/07/01'), by="week") , value=1:26) df_data2 = data.frame(date_input = seq(as.Date('2022/01/01'), as.Date('2022/07/01'), by="week") , value2=3:28) plot1 <- plot_ly() plot1 <- plot1 %>% add_trace(data = df_data1, x = ~date_input, y = ~value , type = 'scatter', mode = "lines", yaxis = "y", line = list(color = '#E64B35FF', opacity = 0.8) , showlegend = FALSE , hovertemplate = ~paste('# Value1: %{y:.0f}<extra></extra>')) %>% add_trace(data = df_data2, x = ~date_input, y = ~value2 , type = 'scatter', mode = "lines", yaxis = "y2", line = list(color = '#4DBBD5FF', opacity = 0.8) , showlegend = FALSE , hovertemplate = ~paste('# Value2: %{y:.0f}<extra></extra>')) plot1 %>% layout( font = list(size = 10), xaxis = list(title = list(text = '<b>Date<b>', font = list(size = 12)) , fixedrange = T, showgrid = FALSE, ticks = 'inside', type = 'date' #, tickprefix = "Week of ", tickformat = '%d %b %y', ticktext = 'test' ), yaxis = list(title = list(text = '<b>Number of value1<b>', font = list(size = 12, color = '#E64B35FF')) , fixedrange = T , rangemode = 'tozero', showgrid = FALSE, showline = T, ticks = 'inside'), yaxis2 = list(overlaying = 'y', side = 'right', fixedrange = T, rangemode = 'tozero', showgrid = FALSE, showline = T, ticks = 'inside' , title = list(text = '<b>Number of value2<b>', font = list(size = 12, color = '#4DBBD5FF'))), margin = list(t = 50, r = 50), hovermode = "x unified" ) The output now looks like this:
So I want to change the date format from the black circled part (and not the ticks)
